Object.observe: prevent observed objects from using fast elements. · 76375de2

rossberg@chromium.org authored Dec 12, 2012

This is necessary because polymorphic stores generally
do not perform a map check but only an instance type check,
which misses out on changes in the observation status.
Unfortunately, there currently is no efficient way in V8
to maintain that optimisation in the presence of Object.observe.

correctly clear the optimized code map even when incremental marking is
running.
